New video and Infographic Explain Why MSG is Perfectly Safe
According to the American Chemical Society (ACS), monosodium glutamate (MSG) has suffered from inaccurate consumer perceptions for too long - so the non-profit organization has decide to put the consumer myths about MSG to rest. In a new video released in August 2014, ACS corrects the myths about MS...>> more
Glutamate is glutamate whatever the source!
Sodium reduction in food products is a major issue on the global health agenda, so manufacturers are continually looking at methods of producing low-sodium products without compromising on the taste or consumer appeal. Since its discovery over 100 years ago, monosodium glutamate (MSG) has been used ...>> more
Glutamate Is Natural
Glutamate is common throughout nature. It is a component of your body and your foods. The taste-imparting property of glutamate has long been used around the world to enhance the palatability of foods.>> more
MSG Safe Use
Over one hundred years ago, Professor Kikunae Ikeda of Tokyo Imperial University discovered the taste that is now recognized internationally as “umami.” It has been established for more than 10 years now that umami, which is the taste imparted by monosodium glutamate (MSG), stands alongside sweet, sour, salty and bitter as one of the five recognized basic tastes.>> more
Glutamate & Taste
A team of scientists in the US have recently discovered a unique mechanism by which certain molecules can drastically enhance the umami flavour - the savoury taste often associated with protein-rich foods such as meat, cheese and seafood.

Umami is one of the 5 basic taste qualities. The umami taste of L-glutamate can be drastically enhanced by 5' ribonucleotides and the synergy is a hallmark of this taste quality. The umami taste receptor is a heteromeric complex of 2 class C G-protein-coupled receptors, T1R1 and T1R3. Here we elucidate the molecular mechanism of the synergy using chimeric T1R receptors, site-directed mutagenesis, and molecular modeling. We propose a cooperative ligand-binding model involving the Venus flytrap domain of T1R1, where L-glutamate binds close to the hinge region, and 5' ribonucleotides bind to an adjacent site close to the opening of the flytrap to further stabilize the closed conformation. This unique mechanism may apply to other class C G-protein-coupled receptors.
Recent advances in the understanding of the biology of taste have found that distinct cell receptors are tuned to detect each of the five basic tastes: sweet, sour, bitter, salty and umami. These receptor cells function as dedicated sensors, helping us to recognise and distinguish key dietary components.

The emerging picture of taste coding at the periphery is one of elegant simplicity. Contrary to what was generally believed, it is now clear that distinct cell types expressing unique receptors are tuned to detect each of the five basic tastes: sweet, sour, bitter, salty and umami. Importantly, receptor cells for each taste quality function as dedicated sensors wired to elicit stereotypic responses.
